Something I was taught. If you have a deeper experience during meditation, you can enhance that experience. Try not to go back into your regular routine for a couple of hours. Don't talk with anyone, don't do any regular activities...maybe read some spiritual books or take a walk. Just try to stay in the spiritual mood. I was taught that the spiritual light received during meditation can take a couple of
hours to be properly absorbed and that if this time is not taken, it lessens the power of the experience.

Also, if the meditation is particularly deep, later that day, you can write a diary entry about it. A poem or song about it is even better.
Then, some months or even years down the road, when you are feeling uninspired, you can read the diary entry for inspiration. You can actually go farther and meditate on the past experience and perhaps recall it to the being a bit.
